A variable displacement swash plate type compressor (hereinafter referred to as a swash plate type compressor) has a slope adjusting mechanism to adjust the inclination of the swash plate.

FIG. 1 is a cross-sectional view of a conventional swash plate type compressor, FIG. 2 is a perspective view showing the inclination adjusting mechanism of FIG. 1, and FIG. 3 is a perspective view of the inclination adjusting mechanism of FIG. 2 viewed from another direction.

1 to 3, a conventional swash plate type compressor includes a cylinder block 2 having a bore 22 formed therein, a rotary shaft 3 rotatably installed through the cylinder block 2, A swash plate 4 coupled to the swash plate 4 and coupled to the swash plate 4 so as to reciprocate within the bore 22 by rotation of the swash plate 4, And a tilt adjusting mechanism 5 for controlling the stroke of the piston 1 by adjusting the inclination of the swash plate 4 with respect to the rotating shaft 3. [

The inclination adjusting mechanism 5 includes a rotor 52 coupled to the rotary shaft 3 and rotated together with the rotary shaft 3 and a first arm portion 44 and a rotor 52 of the swash plate 4, And a sliding pin 58 connecting the second arm portion 524 of the second arm portion 524.

The first arm portions 44 are formed as one unit and the second arm portions 524 are formed as a pair of two opposing sides opposite to each other with the first arm portion 44 interposed therebetween.

The first arm portion 44 is formed with a first insertion hole 442 through which the first arm portion 44 is inserted and the sliding pin 58 is inserted into the first arm portion 44 And a second insertion hole 524a through which the second arm portion 524 is inserted and into which the sliding pin 58 is inserted is formed in the second arm portion 524. Here, the second insertion holes 524a are formed in the pair of the second arm portions 524, respectively.

The first insertion hole 442 is formed in a cylindrical shape so that the sliding pin 58 is rotatable within the first insertion hole 442.

Here, a retainer 59 is provided at one end and the other end of the sliding pin 58 to prevent the sliding pin 58 from disengaging.

The inclination adjustment mechanism 5 is configured such that the sliding pin 58 is rotated inside the first insertion hole 442 and is rotated and reciprocated within the second insertion hole 524a, The inclination of the swash plate 4 is adjusted.

However, in the conventional swash plate type compressor, as the sliding pin 58 moves in a state of being in line contact with the second insertion hole 524a, the stress is concentrated, There is a problem that abrasion occurs in the rotor 52 (more precisely, the second arm portion 524). Thus, there is a problem that the inclination adjusting mechanism 5 causes an unstable behavior different from a predetermined behavior.

More specifically, since the sliding pin 58 is slidably formed in the second arm portion 524 in a state where the sliding pin 58 is fastened to the first arm portion 44, the first arm portion 44 and the second The arm portions 524 are formed so as to overlap with each other, and the second arm portions 524 are formed in a predetermined size (larger than the size of the second insertion holes 524a). Accordingly, as the sizes of the first arm portion 44 and the second arm portion 524 are increased, the material amounts of the swash plate 4 and the rotor 52 are increased and the machining amount is increased, The manufacturing cost of the rotor 4 and the rotor 52 is increased. As the size of the first arm portion 44 and the second arm portion 524 increases, a mass unbalance occurs in the swash plate 4 due to the first arm portion 44, 524 cause mass unbalance of the rotor 52. [ A first counter mass 48 is formed on the opposite side of the first arm 44 in order to eliminate the mass imbalance and a second counter mass 48 is formed on the opposite side of the second arm 524 The material of the swash plate 4 and the rotor 52 is further increased and the amount of processing is further increased so that the manufacturing cost of the swash plate 4 and the rotor 52 is increased, Is increased. As described above, in order to prevent the abrasion due to the line contact between the second insertion hole 524a and the sliding pin 58, the second insertion hole 524a and the sliding pin 58, (58) are subjected to special processing and special heat treatment. As a result, the manufacturing cost of the rotor 52 and the sliding pin 58 is further increased. Further, as the retainer 59 is provided, the manufacturing cost of the inclination adjusting mechanism 5 is further increased.

The weight of the swash plate 4 and the rotor 52 by the first arm portion 44, the second arm portion 524, the first counter mass 48 and the second counter mass 528, The energy required to move the swash plate 4 and the rotor 52 is increased. That is, the driving loss is increased.

The swash plate type compressor according to the present invention comprises a link member that is relatively rotated while being in surface contact with the rotor at one side and relatively rotated at the other side in surface contact with the swash plate, The contact area between the members can be increased. Thereby, abrasion between the rotor and the link member and between the swash plate and the link member is suppressed, and the unstable behavior of the inclination adjusting mechanism can be prevented from occurring.

In addition, the manufacturing cost required for forming the swash plate and the rotor by the link member can be reduced. More specifically, as the link member is provided, the first arm portion of the swash plate and the second arm portion of the rotor are formed so as not to overlap with each other, and the size of the first arm portion and the second arm portion can be reduced as compared with the conventional one. As a result, the amount of material of the swash plate and the rotor is reduced, and the amount of processing is also reduced, so that manufacturing cost of the swash plate and the rotor can be reduced. As the size of the first arm portion and the second arm portion is reduced, the mass unbalance of the swash plate by the first arm portion is reduced, and the mass unbalance of the rotor by the second arm portion can be reduced. Accordingly, the swash plate and the rotor may not be provided with a counter mass for solving mass unbalance. As a result, the material amount of the swash plate and the rotor is further reduced, and the amount of processing is further reduced, thereby further reducing the manufacturing cost of the swash plate and the rotor. As described above, since the abrasion between the rotor and the link member and between the swash plate and the link member is suppressed, special processing and special heat treatment are not required at the contact portion between the rotor and the link member and the contact portion between the swash plate and the link member. Accordingly, manufacturing costs of the swash plate, the rotor, and the link member can be further reduced. Unlike the prior art, the manufacturing cost of the tilt adjusting mechanism can be further reduced as the retainer is removed.

Further, the energy required to move the swash plate and the rotor can be reduced by reducing the weight of the swash plate and the rotor due to the weight reduction of the first arm portion and the second arm portion and the elimination of the counter masses. That is, the driving loss can be reduced.

One end of the rotary shaft 3 is inserted into the axial hole 24 of the cylinder block 2 so as to be rotatably supported and the other end of the rotary shaft 3 is projected to the outside of the swash plate type compressor, Lt; / RTI >

The swash plate 4 and the rotor 52, which will be described later, may be fastened to the intermediate portion of the rotary shaft 3.

The swash plate 4 includes a first annular plate portion 42 formed in an annular shape and a first arm portion 44 protruding from an inner peripheral portion of the first annular plate portion 42 toward a rotor 52 .

The inner circumferential portion of the first annular plate portion 42 is coupled to the rotation shaft 3 inserted into the inner circumferential portion thereof and the outer circumferential portion of the first annular plate portion 42 can be inserted into the coupling hole 12 of the piston 1.

The first arm portion 44 may be spaced apart from the second arm portion 524 to be described later in a direction crossing the first annular plate portion 42 and a second annular plate portion 522 to be described later. That is, the first arm portion 44 may be formed so as not to overlap with the second arm portion 524 described later.

The first arm portion 44 is provided with a first insertion groove 46 which is engraved from the outer surface of the first arm portion 44 and into which a first end portion 542 of a link member 54, Can be formed.

The first insertion groove 46 may be formed in a spherical shape having one side opened. That is, the first insertion groove 46 is in contact with the first curved surface 542a of the first end portion 542, which will be described later, from a point to the inner wall surface of the first insertion groove 46 Can be formed uniformly.
